DUMPING-VVAGON.

Specification of Letters Patent.

Patented Nov. 2, Mild.

Application filed July 113, 1914. Serial No. 850,739.

To all whom it may concern:

Be it known that l, GEORGE a citizen of the United States, residing atMiddletown, in the county of Butler and State of Ohio, have inventedcertain new and useful Improvements in Dumping- VVagons, of which thefollowing is a specification, reference being had to the accompanyingdrawings- This invention relates to new and useful improvements indumping wagons, and particularly to that class in which the materialcarried in the box is dumped through swinging doors at the bottom of thebox.

An object of this invention is the provision of improved means foropening and closing the doors at the bottom of the wagon box, wherebyboth doors are operated simultaneously when it is desired to open orclose the same.

A further object of this invention is the provision of a dumping wagonwhich ineludes a wagon box, to the bottom of which a pair of doors areswingingly connected, means being provided to check the downward andoutward swing of the doors to prevent the same from striking the wheelsof the wagon and to prevent the load which is dumped, from spreadingbeyond the wheels of the same.

With these and other objects in view, my invention consists in the novelconstruction, combination, and arrangement of parts to be hereinaftermore fully described, claimed,

and illustrated in the accompanying drawings, in which,

Figure l is a top plan view of a wa on showing my improved doors andoperating mechanism connected thereto; Fig. 2 is a side elevational viewthereof; Fig. 3 is a rear end view; Fig. 4 is a sectional view on theline l-4t of Fig. 1; Fig. 5 is a fragmentary bottom view of one end ofone of the doors.

Referring more particularly to the drawing, the numeral 1 designates thebody of the wagon which is provided with a wagon box for receiving aload, the box comprising the sides 2, front wall 3, and rear wall 4, andhaving an openbottom which is closed by the swinging doors 5. Connectedto the outer face of each side 2 of the box are pairs of straps 6, thestraps 6 of each pair,

heingconnected toeach side adjacent its forward end, and another pairbeing connected to each side adjacent its rear end. Arranged within eachpair of straps is a keeper or guide bar 7, the opposite ends of thekeepers being offset inwardly and secured to the sides of the boxbetween the straps (3, and the lower end of each keeper terminating nearthe lower end of the box. It will be observed that the keeper or guidebar 7 affords vertically disposed elongated loop members. Secured to theouter face of each door are pairs of transversely extending straps 8,the pairs of straps being spaced apart to substantially the samedistance as the straps (i secured to the sides of the box, the outerends of the straps 8 being disposed angular-1y as at 9 to engage onopposite sides of the keepers 7 the extremities of the angularlydisposed ends of each pair of straps 8 being connected by a pin acarrying a roller 10 which engages between the inner face of one of thekeepers 7 and the straps 6 on the sides of the box.

Rotatably mounted in suitable supports 11 on the body, forwardly of thebox, is a winding shaft or drum 12, the shaft having .a ratchet wheel 13keyed on one end thereof, and loosely mounted on the shaft adjacent thewheel 13, is an operating handle 14, the handle carrying a slidable pawl15 to engage the teeth of the ratchet wheel 13 so that upon rotation ofthe handle in one direction, the shaft is rotated. Connected to suitablehooks 16 which are secured to the rear end of the box adjacent its upperedge, are the rear ends of a pair of door closin chains K 17, the chainsextending downward'y to engage against pulleys 18 which are rotatablysupported upon the rear end 4 of the box, adjacent its lower edge.Rotatably mounted in a yoke connected to each door at its inner edge andadjacent the rear endthereof. is a roller 19, a pair of similar rollersbeing rotatably mounted in yokes secured to the under face of each dooradjacent its inner edge and disposed centrally of its ends, anotherroller 21. being rotatably mounted in a yoke connected to the under faceofeeach door adjacent its forward end.

The chains 17 are passed under the rollers 19 at the rear ends of thedoors and thence over the rollers 20 intermediate of the ends of thedoors, and then under the rollers 21 connected to the forward ends ofthe doors, the chains being then passed upwardly along the front wall 3of the box, the chains till? iti till

htl

ltltl ltlli lltl which is mounted upon the body forwardly of the box. 1

The doors 5 are normally maintained in closed position by operating thehandle 14 connected-to the shaft 12 with the pawl 15 engaged with theteeth of the ratchet wheel 13 so that the forward ends of the chains 17are wound upon the drum until the doors are entirely closed, the doorsbeing held in their closed positions by means of a pivoted pawl whichis'carried by the body of the wagon. It will be seen that when it isdesired to open thedoors 5 of the box, the pawl 15 is merely disengagedfrom the teeth of the ratchet wheel 13, thereby allowing the doors to beopened by their, own weight and the weight of the load interposedthereupon, the doors when opening, unwinding the forward ends of thechains 17 from the drum. The rear ends of, the chains 17 "are preventedfrom swinging side to side when the doors are opened by reason of thepulat their inner edges will cause the outer edges of the doors to rise,owing to the engagement of the rollers 10 withthe guide bars 7, whichchecks the outward swing of the doors, so that the same will beprevented from striking the wheels of the wagon.

Upon further pressure of the load upon the doors, the same will be moveddownwardly with the rollers 10 engaged against the straps 6 connected tothe outer faces of the sides of the box. \Vhen the drum 12 is rotated towind the forward ends of the chains thereupon to close the doors, theengagement of the chains against the rollers 19 and 21 carried upon theopposite ends of the doors will draw the meeting edges of the doorsupwardly to tightly close the doors to receive another load.

Having thus fully described my invention, what I desire to claim andsecure by Letters Patent is In a dumping wagon, the combination with abox and a movable bottom therefor, a vertically disposed pair of spacedand parallel straps carried by each side of the box, a verticallydisposed elongated keeper carried by each side of the box having itsextremities secured to the box between the straps, angularly disposedmembers carried by the bottom and arranged in pairs, the members of eachpair being disposed at opposite sides of a keeper, a pin connecting thefree extremities of each pair of members and disposed through theadjacent keeper, and a roller carried by said pin between the membersand contacting with the keeper and the straps.

In testimony whereof I hereunto afiix my signature in the presence oftwo witnesses.

GEORGE W. SHARTLE.
